No offence but I just looked at your blog and it seems quite spammy. There seem to be more ads than content, its filled with banner ads all over, in-text ads, there's Amazon affiliate links all over the show and to add insult to injury there are dating/adult based ads that show up. Now if I were a reviewer, how are all these ads relevant for an 'NGO'? Sorry but I would reject your application as well. There is only 5 months worth of content up there and even that doesn't really make a lot of sense.
What I would initially is get rid of ALL the advertising, REALLY work on developing your content for readers. Try to add at least 2 bits of content per week, ideally 500 words per article. Ensure that the content actually tries to help in some way or it tries to help solve a problem.
Look at the site and ask yourself, does this site (and advertising) add any value to my readers? If the answer is yes then you're well on your way to getting accepted.
I would get at least 7 months of quality content up there, get rid of the ads, refresh the layout a bit and then try again. It has nothing to do with your nationality or where its hosted, I have several friends from India that have AdSense accounts.
If you focus on quality all the time I don't see why you should have a problem.
Hope that helps
